Submerge planes
I'm having trouble with the following problem, can anyone help? Refer to attached picture.
A 25mm thick steelgate of 15mx8m size, specific gravity of 7.8 is hinged, as shown in the figure below, to store flashflooding water. The density of water, at standard temperature condition, is 990 kg/m3. Compute the water level h for which the gate starts to fall.
